WesWorld

The Mitsubishi Ki-22, Nakajima Ki-53 and Mitsubishi G4M are real world aircraft (with the 'Ki' designation numbers being slightly off due to a few additional planes in the list) so the data in the encyclopedia is the same as given by Wiki. Also these planes, together with the Type 108 use radial engines.

Hrolf said "an air-cooled radial, not a very good comparison to an inline V-12" so they're not quite in the same class. Compared to the historical planes, the 1500 hp radial of the TBN-7 should be no problem at all.

That was; lets strap guns to a racing seaplane

No, that was a "lets strap four 25mm canons and a 7.7mm machinegun to a racing seaplane" moment.

Oh I'm aware of that, I just wanted to post some comparable engines in the 1,500 hp class and others worth noting. Interestingly enough I can't find any specific stats on Wesworld German aircraft engines without doing abit of searching both in wesworld posts and info on the web about real world engines so its abit difficult to get a handle on what Germany has, whats historical and whats not.

You may want to note that the SAE, despite being through a war, where developement was pushed as money played a lesser role, and using all the experience just fields a 1320hp engine as most powerful. And this one has a supercharger for 4000m which is in fact inferior to what many others already field in WesWorld.

This plane was at the very edge of the 5-year rule then in place when I decided which planes will be available in late-35/early-36. However, we then changed to the 3-years rule and so in 1937 this is still the most potent engine. The developement curve in WesWorld otherwise would be too steep - at least from my point of view.

I can just propose to not push the pedal to the medal with every new plane.

Dunno if this will help ....but ages ago I crawled through websites to put together a list of engine parameters by year of service, which I posted in one of RA's threads.

It is not exhaustive or complete, but may be useful for comparison.
It should be born in mind that on-line sources have a bad habit of having multiple HP ratings for the same darn engine, often at the same altitude.
Anyhow here is the section for bracketing the +3 1940.

Yes, there are 1500hp radials, they are young and have a poor P:W ration compared to older radials it seems.
There are plenty of 1000- 1300 hp in lines, again the older smaller engines are somewhat more efficient.

1939: 1000hp Dagger VIII, air-cooled H, unreliable.
1939: 1,130hp/ 1,320lb Merlin X, 27L, reliable.
1939: 995hp/1,065lb Bristol Mercury XV, 24.9L, 4' 3.5"dia.
1939: 1,290hp/ 1,930lb Bristol Hercules I, 38.7L, 4'4" dia.
1939: 1,375hp/ 1,930lb Bristol Hercules II, 38.7L, 4'4" dia.
1939: FW 190 v1, 1550hp BMW 139
1939: FW 190 v1, 1550hp BMW 801
1939: Gnome-Rhone 14R, 1291hp
1939: 1030hp /1,300lb Gnome-Rhone Mistral Major 14N, 38.7L, 4.3' dia.
1939: Gnome-Rhone 14R, start 1578hp MAX


1940: 1,030hp/ 1,320lb Merlin II, 27L, reliable.
1940: USN 2-stage supercharger.
1940: 2,200hp / 2,502lb = 59.9hp/L Napier 3.84' h x 3.33'wide.
1940: 1,300hp/ 1520hp Hispano-Suiza 12Z-17, 36L,
1940: 1,084hp/1,036 lb. Hispano-Suiza 12Y-51, 36L, 3.1 ft high x 2.5 ft. wide x 5.7 ft long.
1940 : 1,200hp/1,467 P&W R-1830-76 Twin Wasp, 31.63L, 4.2'dia.
1940 : 1,000hp Wright R-1820-G205A Cyclone
1940 1,100hp / 1,365lb, M-105, 35L,
1940: 1,500hp/ 1,930lb Bristol Hercules XI, 38.7L, 4'4" dia.

1941: 1,730hp / 2,707lb BMW 801-C, 41.8L, 4.2'dia.

1941 : Nakajima Sakae 21, 1,130hp
1941: 1,250hp /1,595 lb V-1710-115 Allison prototype. 28L, 2.45' h x 3.05'wide.
1941: 1,322hp / 1,587lb Jumo 211F 35L 3.5 ft high x 2.7 ft. wide x 7.2 ft. long.

Huh? According to your encyclopedia you fielded the 1320 Hp engine in 1935...

That´s what I said. I used it in for my 1935er stories when the 5-year-rule was in place. But since then we a) decided to go with 3-years and b) I changed my mind and tried to avoid a steeper curve.

That´s why in 1937 (Talons) the 1320hp engine is still the most powerful production engine in the stocks of the RSAF.

It depends somewhat on the size and weight of the engine. Italy currently has two high powered engines of over 1500hp, the Alfa-Romeo 135 of 1700hp which is an 18-cylinder radial (and historical if of slightly greater power) and the Isotta-Fraschini Asso 1500 of 1930hp both of which are very large and heavy and not particularly suitable for fighters.

Hopefully the Alfa Romeo will be more reliable than historical, as it seems that it was never fielded in any numbers.

As far as what Germany is doing, right now all the engines Germany uses are historical except for the Jumo-208 diesel radial that's used on the Do-24 seaplane, and the Fw-205 and the Ju-152 transports. The BMW-801 (currently available in the A, B, & C versions) is the highest powered engine Germany has, at 1560 hp, but it's suffering through it's historical cooling problems. After that we drop down to the new DB-601E, historically rated at 1450 PS, and the Jumo-211E at 1200 hp (the Jumo-211F will be available in late 1937).

There were some initial production difficulties involving mechanical failures (the gear cam ring IIRC) but in later tests the Germans rated it as considerably more reliable than the BMW 801 and R-1820. Production of large numbers is a problem common across all Italian industry, a fair part caused by essentially no wartime mobilisation of industry.

The CAC-15 is usually overated, mostly because the often quoted speed of 502mph was achieved in a dive. Level speed was much lower. Spitfire XIV has large advantages in turn and climb but less range, though that could be rectified relatively simply as per 20 and 40 series.

What does the CAC-15 have to do with the Mexican C-15?

I have no idea what aircraft you're talking about. Even more strangely, the internet didn't give me answers either.

Edit; rechecked and it's the GW 105/Bf 109.

Sorry, missed this thread.

The C-15+ should be entering service in early 1938. However the final production model will be delayed by the Yugoslav War (to incorporate lessons) and won't enter service until late 1938.
